The First Genomic Analysis of Visna/Maedi Virus Isolates in China [PDF]

Frontiers in Veterinary Science, 2022
Visna/Maedi virus (VMV) is a neglected pathogen that damages sheep and goats' nervous and respiratory systems. The virus was discovered 80 years ago and has been endemic in China for nearly four decades; nevertheless, there is little information ...

Ovine TRIM5α can restrict visna/maedi virus. [PDF]

J Virol, 2012
ABSTRACT The restrictive properties of tripartite motif-containing 5 alpha (TRIM5α) from small ruminant species have not been explored. Here, we identify highly similar TRIM5α sequences in sheep and goats. Cells transduced with ovine TRIM5α effectively restricted the lentivirus visna/maedi virus DNA synthesis.

Seroprevalence of Visna-Maedi Virus (VMV) and Border Disease Virus (BDV) in Van province and around [PDF]

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2018
The present study investigated the seroprevalance of Visna Maedi Virus (VMV) and Border Disease Virus (BDV) infections in sheeps in regions in and around Van province, Turkey. Sample materials were taken from 360 sheep sent to slaughterhouses around Van.

Role of alveolar macrophages in respiratory transmission of visna/maedi virus. [PDF]

J Virol, 2008
ABSTRACTA major route of transmission ofVisna/maedi virus(VMV), an ovine lentivirus, is thought to be via the respiratory tract, by inhalation of either cell-free or cell-associated virus. In previous studies, we have shown that infection via the lower respiratory tract is much more efficient than via upper respiratory tissues (T. N.

Amplicon sequencing with Oxford nanopore technologies as a diagnostic alternative for small ruminant lentiviruses in sheep [PDF]

Scientific Reports
In Europe, Maedi-Visna disease has high prevalence rates at the individual and flock levels, respectively, and is regarded as one of the most significant infectious disease in sheep.

Identification of the ovine mannose receptor and its possible role in Visna/Maedi virus infection. [PDF]

Vet Res, 2011
Abstract This study aims to characterize the mannose receptor (MR) gene in sheep and its role in ovine visna/maedi virus (VMV) infection. The deduced amino acid sequence of ovine MR was compatible with a transmembrane protein having a cysteine-rich ricin-type amino-terminal region, a fibronectin type II repeat, eight tandem C-type lectin ...

Investigation, management and control of a maedi outbreak in Norway in 2019-2020 [PDF]

Acta Veterinaria Scandinavica
Background Visna-maedi is a notifiable disease in Norway, and eliminating the disease is a national goal. The import of sheep into Norway is very limited, and strict regulations apply to the movement of small ruminants between flocks and within defined ...

Pathological, molecular, and serological study of small ruminant lentiviruses in Jordan [PDF]

Veterinary World, 2022
Background and Aim: Maedi-visna is a chronic viral disease of sheep with worldwide distribution causing substantial economic losses to the small ruminant industry. Pneumonia and mastitis are the main manifestations of the disease.
